INVENTOR and useful y nutren srarns rarnnr orricn i EDWARD HOVE, OF MARYSVILLE, CALIFORNI To all (whom t may concern.'

Beit known that I, EDWARD Hove, a citizen of the United States, residing at Marysville, in the county of Yuba and State of California, have invented certain new Improvements in Lubricating Mechanism, of which the following is a specification.

This invention relates to lubricating mechanism forinternal combustion engines and particularly to the type which supplies the lubricant to the crank case-of the engine for distribution and use in accordance with the combined splashing and vacuum or suction principle.

I aim to provide a novel, improved, sim-` y plited. and more efcient form of lubricator for the uses set forth and one possessing the advantages and attaining the objects hereinafter described and set forth in connection with accompanying drawings wherein one preferred embodiment is illustrated.

Figure 1 is a` vertical sectional view through my improved lubricating mechanism, and an internal combustion engine with which it is associated; and

Fig.` 2 is a cross sectional view on the line 2 2 of F ig.V l.

Referring specically to the drawings, a conventionaltype of internal combustion engine is illustrated in Fig. l, of which the crank mechanism is shown at 3 and mounted `within a-crank case i to which a suitable lubricant supply pipe 5 leads.

The supply pipe 5 in turn leads from a lubricant reservoir 6 of any preferred cony struction, which preferably has a portion of its side wall adjacent the lower end tapered inwardly as at 7. A manually operable screw plug 8 serves as a removable closure for the reservoir 6 and is screw threaded thereto as at 9. A gage preferably in the f form .of the usual glass or transparent tube from the ably mounted in the bearings 14 and 15, is

is provided at 10 so that the contents of the reservoir may be gaged'ancl readily ascertained.

` ing a central opening at 12 serving as a seat for a flat frusto-conical valve 13. Spaced from the plate `11 and formed integral with the outer wall of the reservoir 6 is a spider or bearing 14. A bearing 15 is underhung top wall of the reservoir 6. Slid- Specification of Letters Patent.

LUBRICA'I'ING MECHANISM.

a vertically movable rod 16 which serves as .a stem for and carries the valve 13. Sur- Asupp y of lubricant from the reservoir through the pipe 5 to the case Ll. It will be noted, however, that the closure member 8 is provided with a cavit f or recess at 18 into which the stem 16 extends.

The lubricant is supplied by gravity from the reservoir 6 through the pipe 5 into the crank ease 4. The valve 13, however, is normally in engagement with its seat so as to cut off the supply of lubricant to the crank case but when the cap or plug 8 is screwed into the reservoir to a suflicient extent, it depresses the valve stem 16 and accordingly the valve 13 as shown in Fig. 1 so as to present an escape passageway for the lubricant. After the desired quantity of lubricant has entered the crank ease 4, the top 8 may be unscrewed or entirely removed so that the spring 17 will force the valve 18 into engagement with its seat l2 and prevent further supply of lubricant to the crank case. It will be realized that the lubricant contained in the crank case will be splashed through operation of the crank and associated parts therein and in addition will be drawn into the cylinders on the suction strokes of the piston.

While I have shown one specific embodiment of the invention, yet I do not limit myself thereto since changes may be made without departing from the spirit and scope of the invention.

I claim:

l. A lubricating device of the class described having a reservoir, a valve to control the supply of lubricant therefrom, a closure member for said reservoir, and said member being operable independently of and against said valve to position the valve.

2. A lubricating device of the class described having a reservoir provided with an outlet valve, a rod for said valve extending from opposite faces thereof, bearing means for the rod, a spring on one side of the valve urging it to its seat, and means on the other side of the valve movable independently of and relatively to the valve Y :jgid's'teruto :ur-ge the yalve towardjitjs seat,
